Happy New Year!
After these annoying, but good looking failed things:
I was able to more or less put together a road which resembles how the new one will look like together with the terrain:
So still a lot of work to do, but at least there is something new to see now :D
If you want to try this version, you can access it if you go into your steam library then right click the game, select properties, then in the betas tab from the drop down menu select "beta - upcoming version test"
This is just a test version with no save-load, no main menu, no loot and buildings near the road, and the road is just 20km long, but you have plenty of fuel, so you can go and explore the huge desert.
Thank you again for playing and your patience! ːsteamhappyː
